Necessity. Input must be necessary to use e.g. on specific crops, in specific regions orunder specific conditions from the viewpoint of yield, product quality, environment safety,human and animal welfare.2. Nature and mode of production. The origin of input should usually be organic – vegetative,animal, microbial; or mineral. The ingredients of the input may undergo processes such as,mechanical, physical, enzymatic, action of microorganisms. The collection of raw materialsshall not affect the stability of the natural habitat nor affect the maintenance of any specieswithin the collection area.3. Environment. The input shall not be harmful or have a lasting negative impact on theenvironment. Nor the input shall give rise to unacceptable pollution of surface or groundwater, air or soil. Input shall not contain harmful manufactured chemicals. All inputs shall bedegradable to CO 2 , H 2 O and or to their mineral form. Inputs with a high acute toxicity tonon-target organisms should have a maximum half-life of 5 days. Natural substances usedas inputs which are not considered toxic do not need to be degradable within a limited time.Mineral inputs should contain as few heavy metals as possible.- 48 -
(Seed Health Management for Better Productivity)4. Human health and quality. Inputs shall not be harmful to human health, and shall not havenegative effects on the quality of the product.5. Ethical aspects – Animal welfare. Inputs shall not have a negative influence on the naturalbehavior or physical functioning of animals kept at the farm.6. Socio Economic Aspects. Consumer’s perception. Inputs should not interfere with ageneral feeling or opinion about what is natural or organic.General guidelinesNo single strategy is likely to be successful on its own. Effective control relies on theeffective interactions between many factors.1) Adopt a variety of cultural methods to control plant diseases; including Organic manuringand crop nutrition, rotation design, and choice of crop varieties appropriate to location.2) Adopt measures, such as, crop isolation where there is a danger of contamination fromneighboring fields, and rouging of diseased plants affected with seed borne diseases within fields. Insect borne viruses are best controlled by controlling the transmitting insects.3) Adopt direct biological and mechanical controls. Use plant extracts to treat the soil or theplanting material. Air bone diseases can be treated by the use of foliar sprays and otherpermitted products.- 49 -
